Sliding Plug Connector with Shield Can for Miniaturization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connector assemblies are difficult to miniaturize due to their height and lack effective electromagnetic wave shielding, and they struggle to simultaneously connect multiple cables and a circuit board.
Innovation Solution
A plug connector design where the signal pin is slidably inserted into a receptacle connector, featuring a shield can and insulating member to expose the signal pin's lower surface, with a plug shell and additional shielding elements to minimize height and enhance electromagnetic wave shielding, allowing for parallel arrangement of signal pins and simultaneous connection of multiple cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a plug connector is vertically fastened to a receptacle connector, then the connector assembly can be assembled, but the height of the connector assembly increases making miniaturization difficult
Solution Approach 1:
The plug connector is changed from a vertical fastening orientation to a horizontal sliding insertion orientation relative to the circuit board. This dimensional change allows the connector assembly to have a lower profile while maintaining assembly functionality, directly resolving the height reduction goal.
Solution Approach 2:
The connection method is changed from a static vertical fastening to a dynamic sliding insertion mechanism. The plug connector slides horizontally into the receptacle connector along the circuit board surface, enabling miniaturization while maintaining reliable electrical connection.
2Object-affected harmful factors
If a plug connector is vertically fastened to a receptacle connector, then the connector assembly can be assembled, but electromagnetic wave shielding is ineffective
Solution Approach 1:
The shield can is nested within the plug shell, creating a layered shielding structure. The signal pin is surrounded by the shield can, which is in turn enclosed by the plug shell, providing multiple levels of electromagnetic wave shielding while maintaining a compact horizontal profile.
Solution Approach 2:
The shield can is positioned locally around the signal pin to provide targeted electromagnetic shielding where it is most needed. The shielding structure is concentrated around the critical signal transmission area rather than requiring a tall overall structure.
3Adaptability or versatility
If a conventional connector assembly structure is used, then assembly is simple, but simultaneous connection of multiple cables and circuit board is difficult
Solution Approach 1:
The plug connector design with multiple signal pins arranged in parallel allows a single connector assembly to simultaneously connect multiple cables to the circuit board. Each signal pin can accommodate a separate cable, providing multi-functionality in a unified horizontal structure.
Solution Approach 2:
The connector assembly is segmented into multiple independent signal pin channels, each capable of handling a separate cable connection. This segmentation allows simultaneous connection of multiple cables while maintaining a compact integrated structure that slides horizontally into the receptacle.
